Cory Cat Aquarium Fish

Corydora or Cory Catfish For Sale

These specialty freshwater catfish are members of the South American Corydoras genus. Corys are a temperate & tropical catfish in the armored catfish family, Corydoradinae. They may be referred to under many nicknames such as corydorases, cories, cory cats or cory catfish.

Cory Cats are some of the most peaceful and entertaining scavengers for a freshwater aquarium, and will thrive in a wide range of water conditions. These catfish are very energetic scavengers that remain relatively small. Because of their small size, they are perfect for keeping the substrate clean in a smaller freshwater community aquarium or nano tanks. There are over 150 species of this genus!

Corys are generally found in small streams along the margins of larger rivers in marshes & ponds in South America. They are native to slow-moving and almost still streams & small rivers of South America where the water is shallow & very clear! Most cory species are bottom-dwellers, foraging in sand, gravel, or detritus for waste. You can find corys on the banks and sides of the streams which are covered with dense plants and algae. Corys can inhabit a wide variety of water types. They can only tolerate a small amount of salt, some species tolerate none at all. They are often seen in shoals*. Most species prefer being in groups and many species are found in schools of hundreds or even thousands of individuals, usually of a single species but occasionally with other species mixed in. Unlike most catfishes which are nocturnal, corys are active during the daytime.

What's the differenced between Schooling & Shoaling?
Actually, it's a type of collective behavior by fish. Any group of fish type that stays together for social reasons is said to be shoaling. If the shoal is swimming in the same direction together, it is then called Schooling. Fish can get many benefits from shoaling which include a better defense against predators. Think about it: if fish swim in large schools, it is less likely any one of them will be eaten! It also helps fish find food, as well as a mate! Schools of fish will even swim faster than a lone fish.
